An object of the invention is to provide a ship
streamlined in construction
and, therefore, eco- `

iloating units may be loaded with other portions
of the ship so constructed as to provide freight
handling space.
Another object of the invention is to _provide a

By the provision of the carrier as specifically 30
described, barges suitable for use _in a harbor or
for use on inland lakes, rivers and canals may >
be directly loaded o_n the ship while provisions
are made for elsewhere carrying freight, thus
economizing in the use of space and making the 35
carrier an efficient transportation device.
